A New Species

We describe and illustrate Sedum lipingense (Crassulaceae), a new species of stonecrop found in the limestone areas of SE Guizhou, China. Based on the presence of adaxially gibbous carpels and follicles, this taxon belongs to sect. Sedum S.H. Fu. The new species superficially resembles S. subtile Miquel and S. bulbiferum Makino but differs from these two taxa in its development of a basal leaf rosette during florescence. The nrDNA internal transcribed spacer (ITS) sequences also support the claim that this plant is a new species in the Sedum genus.

A New Species

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Three New Species

Three new species of Russula collected from southern China are proposed based on morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Russula bubalina sp. nov. is characterized by cinnamon buff to pink pileus with striate margin, interveined and forked lamellae, basidiospores with warty ornamentations not forming reticulum, hymenial cystidia becoming brown in sulphovanillin (SV) and slender terminal cells in suprapellis. R. pseudobubalina sp. nov. is closely related to Russula bubalina in macro-morphology, but it can be recognized by its unforked lamellae, shorter cheilocystidia, bigger basidia and basidiospores with lower ornamentations. Russula subatropurpurea sp. nov. can be recognized by the purplish brown pileus, mild-tasted and white context changing to light purplish red with FeSO4, white and forking lamellae without lamellulae, long hymenial cystidia becoming brown in SV. Both morphological and phylogenetic analysis consistently confirmed the distinct positions of three new species in subg. Heterophyllidia subsection Heterophyllinae.

A New Species

Russula subrutilans sp. nov., a new species of Russula is described from southern China. It is unique for having buff pink to light congo-pink pileus, distant ventricose to subventricose lamellae with rare lamellulae, globose to broadly ellipsoid spores with bluntly conical warts forming a partial reticulum, and narrowly clavate to clavate cheilocystidia and pleurocysitidia with variable tips. Phylogenetic relationships among the new species and other closely related species in the genus are inferred based on the internal transcribed spacer (ITS) region.

Pilea nonggangensis Y. G. Wei, L. F. Fu & A. K. Monro, a new species from Guangxi, China is described and illustrated. The new species is morphologically most similar to P. basicordata from which it differs by being dioecious, having peltate leaf blades, membranous stipules, paired inflorescences and larger bracts. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid trnL-F intron spacer (trnL-F) DNA sequence data from the new species and 20 local congeneric species are used to resolve the systematic position of the new species within Pilea. Despite vastly different morphology the molecular evidence suggests that P. nonggangensis is most closely related to P. pseudonotata. A Global Species Conservation Assessment classifies P. nonggangensis as Vulnerable (VU).

Allium dönmezii is described as a new species from east Anatolia, Turkey. The molecular marker ITS (Internal Transcribed Spacer of nuclear ribosomal DNA) confirms that the new species belongs to A. sect. Melanocrommyum. The diagnostic characters of the new species are morphologically compared with the related A. woronowii, A. serpentinicum, and A. moderense, as well as with A. rothii and A. chrysantherum. In addition, the ITS regions of A. purpureoviride and A. chrysantherum were sequenced and uploaded on GenBank for the first time.

A new species of Polyporales, named as Skeletocutis yunnanensis, was collected on angiosperm wood in northern Yunnan Province, southwestern China. It is described based on morphological characteristics and molecular evidence. The species belongs to the Skeletocutis subincarnata complex, but differs morphologically from all known species of the genus by white, cream to buff pores surface, angular pores mostly 5–6 per mm with entire mouths, a dimitic hyphal structure both in trama and subiculum, generative hyphae in whole basidiocarps covered by fine crystals, skeletal hyphae unchanged in KOH, not agglutinated, allantoid basidiospores measured as 3.5–4.5 × 1.0–1.2 µm, and growth on angiosperm wood. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the new species grouped with Skeletocutis and nested in the tyromyces clade.

A New Species

Elatostema qinzhouense L.F. Fu, A.K. Monro & Y.G. Wei, a new species from Guangxi, China is described and illustrated. Morphologically, E. qinzhouense is most similar to E. hezhouense from which it differs by having smaller size of leaf laminae, fewer and smaller staminate peduncle bracts, longer pistillate peduncle bracts and a larger achene. This result is supported by the molecular evidence. The phylogenetic position of the new species within Elatostema is evaluated using three DNA regions, ITS, trnH-psbA and psbM-trnD, for 107 taxa of Elatostema s.l. (including E. qinzhouense). Bayesian inference (BI) and maximum likelihood (ML) analyses each recovered the same strongly supported tree topologies, indicating that E. qinzhouense is a member of the core Elatostema clade and sister to E. hezhouense. Along with the phylogenetic studies, plastid genome and ribosomal DNA (rDNA) sequences of the new species are assembled and annotated. The plastid genome is 150,398 bp in length and comprises two inverted repeats (IRs) of 24,688 bp separated by a large single-copy of 83,919 bp and a small single-copy of 17,103 bp. A total of 113 functional genes are recovered, comprising 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. The rDNA is 5,804 bp in length and comprised the 18S ribosomal RNA partial sequence (1,809 bp), internal transcribed spacer 1 (213 bp), 5.8S ribosomal RNA (164 bp), internal transcribed spacer 2 (248 bp) and 26S ribosomal RNA partial sequence (3,370 bp). In addition, the chromosome number of E. qinzhouense is observed to be 2n = 26, suggesting that the species is diploid. Given a consistent relationship between ploidy level and reproductive system in Elatostema, the new species is also considered to be sexually reproducing. Our assessment of the extinction threat for E. qinzhouense is that it is Endangered (EN) according to the criteria of the International Union for Conservation of Nature.

A New Species

A new species Tremella zhejiangensis is described from southeastern China based on phenotypic and molecular evidence. The species is characterized by soft gelatinous, yellowish brown to brownish orange, cerebriform basidioma when fresh, thin-walled, globose to subglobose or broadly ellipsoid basidia with a basal clamp connection, globose to subglobose basidiospores measuring 15.0–19.0 × 14.0–17.5 µm with obvious apiculus, and growth on rotten wood of Liquidambar formosana. The phylogeny of Tremella s.s. is constructed using methods of Maximum Parsimony, Maximum Likelihood and Bayesian Inference analyses based on the combined internal transcribed spacer regions (ITS) and the large subunit (nLSU) dataset. The results indicate that T. zhejiangensis forms a lineage independent of other species of Tremella s.s. An illustrated description of the new species is provided and related species are discussed.

A New Species

A new species of endophytic fungus, described herein as Tulasnella phuhinrongklaensis, was isolated from a root of a terrestrial orchid, Phalaenopsis pulcherrima, in Phitsanulok Province, Thailand. This species is characterized by its cream to white colonies, branched chains of spherical to ellipsoid monilioid cells and absence of sclerotia. The uniqueness of the species was confirmed by a phylogenetic analysis of combined sequences of internal transcribed spacer (ITS) and large subunit region (LSU) of ribosomal DNA, and a nucleotide divergence of the ITS sequences. The phylogenetic result showed that T. phuhinrongklaensis formed a monophyletic lineage clearly distinct from other Tulasnella and Epulorhiza species, the asexual morph of Tulasnella. The nucleotide divergence of ITS sequences in the new fungus ranged from 50.66–57.93% in genera Tulasnella and Epulorhiza. A description and illustrations of the new species are provided.
